The lithium abundance in star with and without planet companions are compared. Stars with same age, metallicity and effective temperature were used. The comparison shows that Li abundance of the planet-harboring stars are indistinguishable from those wit hout object in orbits detected. Our result is in agreement with the conclusion to that arrived at by Ryan (2000, MNRAS, 316) but is in opposite to the conclusion arrived by Israelian et al. (2004, A&A, 414) who found differences in the lithium abundance, but only in a reduced range of effective temperature. We compare rotational velocities in order to check the hypothesis that the circumstellar disk which formed planets helped torsionally brake the parent stars during the pre-main sequence helping to stars to destroy lithium efficiently. Both results confirm that Li abundance in host stars of exoplanet are normal.
